"AUTOMATIC FIRE-EXTINGUISHEFL .SPECIFICATION forming" part of Letters Patent No.A 261,709, dated July 25, 1882, Appncauon mea May 2, 1882. (No model.)

' zen of the United States of America, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in AutomaticFire-Extinguishers; and I do herebydeclare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and,

to letters or figures of reference marked thereon, which form a'part of this speciiication.

My invention relates to certain improvements in 'automatic tire extinguishers.

An objection is urged against automaticreextinguishers wherein the cap which covers the distributer is firmly secured with solder to its base, because of the fact that the Water contained in said extinguisher, by reason of the presence therein of vegetable and other impurities, deposits ased'iment in and around the working parts of the extinguisher, which prevents its proper working upon the occasion ota fire, and which at other times cannot be removed and the parts be putinworkingcondition without unsoldering and removing the cap.

The purpose of my invention is to overcome this objection by providing an extinguisher in which the cap may be readily removed at pleasure, so that the working parts of the extinguisher may be examined and cleansed, if 'necessary, and the cap replaced.

To these ends my invention consists of the parts substantially as hereinafter described, and particularly pointed out in the claims.

' Referring to the drawings, Figure lis a vertical section of my improved automatic fireextinguisher. Fig. 2 is an elevation with the cap, with its base-plate removed. Fig. 3 is a plan view of Fig. 2, and Fig. 4 is an elevation, showing the cap removed from its base-plate and above the distributer and the base-plate secured to the base.

Corresponding parts in the several figures are denoted by similar letters of reference.

In the annexed drawings, A marks the base of my improved automatic ire-extinguisher,

provided with a depending portion, A', sothat it may be fitted in thepipe which conducts the fluid-supply'to the distributer.

B marks the neck, secured toor forming part l ofthe base, having ports, and provided with` the bottom of the distributer, as clearly shownl in Fig. 2, and that orifices l) are made, one in each corner, in the top of said distributer, as shown in Fig. 3. By this change the distributer is capable of much better results for the reason that the water will be thrown farther as the perforaticns decrease in size., wherebyY the surface to be protected will be more thoroughly covered; and, further, the openings in the top of the distributer permit water to be projectedagainst the ceiling of the room containing the distributer, which in turn falls to the oor below the extinguisher, whereby Wa` ter will be thrown over the entire surface to be protected -by said extinguisher.

The base A is turned down or cut away at its ed ge to provide the lateral llange a and the central projecting disk, a', the latter having a screw-thread on its periphery, as shown.

-E represents the cap, secured to its baseplate e with solder fusible at a lowl temperature, the said base-plate provided with an interior screw-thread, and the whole adapted to be fitted over the distributer to permit the base-plate to be screwed onto the base, as clearly shown in Fig. 1.

In the present instance thebaseplate e abuts against the bottom of the cap and an annular portion extends a slight distance into said cap and is secured to the inside thereof with fusible solder 5 also, the base-plate has a polygonal peripheral surface to enable it to be readily screwed on or off the base when desired. By thus securing the cap to the baseplate with solder and then screwing the latter onto the base I am enabled to remove the baseplate, with its cap, from the base at any time, to permit an inspection ofthe distributer. To

ICQ

.make such inspection the water must be shut C off from the system of pipes ora portion thereof, as the case may be.

In the event of a fire the heat, when sufficient, will melt the fusible material joining the cap to the base-plate e, when, by reason ofthe pressure of the water in the pipes, the cap will be thrown oft' and the distribnter be uncovered, the base-plate remaining fastened to the base, as before.

A paoking-annulus, F, preferably made of soft metal, is interposed between the baseplate e and the lateral flange a, of the base to provide a water-tight joint, though I do not consider the packing-annulas an essential feature of my invention, since, if desired, a taper screw-thread may be eut on the base and the base-plate, instead of that now shown, to accomplish the same result. Though I do not wish to so limit myself, I prefer to secure the cap to the base-plate e with solder fusible at a temperature of about 1000 to 155O Fahrenheit.

The under side of the base A is cut away, as at G, to facilitate the melting of the fusible material and to provide lightness.

While I have shown and described the baseplate as sere-wed onto the base, it is evident that the essen tial element of my invention will be preserved if other means are provided for detachably connecting said base-plate to the base A.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. The Icombination, with a base provided with a distribut'er designed to spread water or other Huid, of a cap adapted to cover and protectthe distributer, and a base-plate secured with low usible material to the cap-and detaehably fastened to the base, as and for the purpose set forth.

2. The combination, with the screw-threaded base provided with a distributer designed to spread water or other uid, of a cap adapted to cover and protect t-he distributer, and secured with low fusbie material to a baseplate, and the base plate provided with a screw-thread, substantially as and for the purpose set forth.

3. The combination, with the screw threaded base provided with the lateral flange, and a distributer designed to spread water or other fluid, of the cap, the base-plate having the screw-thread and the polygonal peripheral surface, and a packing-annulus, substantially as and for the purpose set forth.

4. A revolving distributer having a serie-i of perfor-ations or fluid-exits in its side of progressively greater diameters from the top to the bottom of the distributer, substantially as set forth.

5. The combination, with a base provided with a d-istributer designed to spread water or other fluid, and a cap adapted to cover and protect the distributer, of an interposed plate detachably fastened to said base and firmly secured to the cap with a low fusible material, as and for the purpose set forth. p

In testimony whereof I affix my signature in presence of witnesses.
